LOOPBACK MODE...
The
SP505
is equipped with two loopback
modes. Single-ended loopback internally
connects V.28 driver outputs to V.28 receiver
inputs. The signal path is non-inverting and will
support data rates up to 120kbps. The propaga-
tion delay times are as specified in the electrical
specifications. To initiate a single-ended
loopback, the code "1010" should be written to
the driver decoder. Differential loopback is
implemented by applying "1011" to the driver
decoder. This internally connects V.11 driver
outputs to V.11 receiver inputs. The signal path
again is non-inverting; the differential loopback
data rate can be at least 5Mbps.
Under loopback conditions the receiver decoder
is disabled. While the
SP505
is in either single-
ended or differential loopback mode, the driver
outputs are tri-stated and the receiver inputs are
disabled.
